Calculate the perimeter of a square with a side length of 8 inches.

To find the perimeter of a square, you use the formula:

[ \text{Perimeter} = 4 \times \text{side length} ]

In this case, the side length of the square is 8 inches. Applying the formula:

[ \text{Perimeter} = 4 \times 8 = 32 \text{ inches} ]

Thus, the perimeter of the square is 32 inches. This is the correct answer because it accurately reflects the calculation based on the geometric properties of a square, which consistently has all four sides of equal length. The perimeter, therefore, is simply four times the length of one side.
